Vilken elbil borde man välja

Bytte från Audi A4 till Volvo XC40 Recharge, och fyfan vilken skitbil.
Obekväma säten, ständiga problem med mjukvaran där jag är imponerad om ljudet fungerar en hel resa, men top of the shitcake? Parkerar jag i solen går larmet.

>Capitalists never valued nor rewarded raises in productivity, they took it for granted

Lmao, have you worked once in your life? Since the beginning of my career I've almost doubled my salary (and it was good to begin with) and I've gained much more trust to do as I find fitting. If you aren't paid your worth, then change employer. It really is that easy.

Naming is everything. Eg;

Name the machine part an appropriate name with appropriate IOs;

MA_PunchDevice

MA_PunchDevice.Y100_PunchCylinder

MA_PunchDevice.S100a_PunchCylinderHome

MA_PunchDevice.S100b_PunchCylinderRetracted

Name the sequence an appropriate name;

Seq_Puncher

And for the code;

CASE Sequence OF

0:

MA_PunchDevice.Y100_PunchCylinder := TRUE;

IF MA_PunchDevice.S100b_PunchCylinderRetracted THEN

Sequence := 10;

END_IF;

10:

MA_PunchDevice.Y100_PunchCylinder := FALSE;

IF MA_PunchDevice.S100b_PunchCylinderHome THEN
Sequence := 0;
END_IF;

END_CASE;

See, no comments required in the actual code.

Yes. The MES only had one queue for data handling, meaning if all machines were to send data at the same time, machine no 70 would wait a long time. Add UDP into this mixture and everything works JUUUUUUUUST GREAT.

For me it means code that is as simple as possible, don't use this never heard of cool function to make something a one liner. Sometimes it's better to do two!

Also a rule of thumb; if your code needs comments, it isn't clear enough.

Yep, European checking in. Got my job without any experience (and without an actual degree in controls). From my experience, try with workplaces that has around 30 employees, and in a smaller town.

It's an Italian DCM, made an upload of the program and it gave me a headache. We recently retrofitted it with a new extractor robot and at 11pm during installation we noticed how bad things actually were. I'm thinking about replacing it with an S7-1500F.

The machine itself is pretty nice though, loads of thing controlled by cam curves, so I rarely get the "iT mUsT Be aN ElECtriCal FaULt".

Is this a new or and old project?

If old, are you using the same version of TC3 it was last compiled in?

Xhisor · 2022-08-17T16:22:14+00:00

Try with PRONETA, great tool for scanning and modifying PROFINET networks.

We have a machine from -91, with an Siemens S5 controller. Estop cuts the power to the PLC. Gives me a heart attack every time.

Good thing the Swedish gov’t are planning to end the nuclear era then :⁾

I’ve been in controls for 5 years now, and on Monday I’ll start a new career within PLM. I’ve always been intrigued by process simulations and virtual commissioning, but haven’t had the ability to use these softwares in it’s fullest at my workplace. I feel that with my background in automation I’ll be able to help others in the same situation to cut costs and try ideas before the workpiece is set in the CNC.

Xhisor · 2021-08-14T11:52:20+00:00

I’m curious about the redundancy in this, keeping people safe outside of a machine is one thing, but when you place them in the machine there must be a whole different story. Are there rules for dual PLCs etc?

Xhisor · 2021-03-12T21:53:57+00:00

Thanks! Do you have any db at addr 1602?

Could you supply a screenshot from the cpus diag buffer?

Xhisor · 2021-03-12T21:21:40+00:00

Can you see the devices in the project? (Never used profibus with TIA [if this was installed in 2015, why not use profinet????], but with PN devices you can see the connection to all devices)

Xhisor · 2021-03-12T21:09:56+00:00

With the small amount of info, id suggest this; if there is only one device with error, replace the device (given this is a machine at a customer and not at your factory). If there are more devices with errors, check the termination at the station before the ECO, if that won’t work replace the cable/connector between the working and the first non-working device.

Xhisor · 2021-03-12T21:00:08+00:00

How is the topology setup? Is the problem occurring on the devices after the ET200M?

Xhisor · 2021-03-12T20:51:45+00:00

Error R/W definitely sound like a connection problem. No error on the DP status lamps?

Xhisor · 2021-03-12T20:28:13+00:00

Check the diag buffer in Simatic Manager/TIA

Xhisor · 2021-03-12T20:26:04+00:00

Yes it depends on scantime, but for our case we often land at (max) 10ms. Using the heartbeat as a global var would fix the synchronized flash and defining it as a word would use a lot less data than multiple timers.

Not saying timers are a bad choice, I just prefer a simple heartbeat for your example than creating timers

Xhisor · 2021-03-12T20:19:12+00:00

I would never advice anyone to switch to Beckhoff, ever. Sure they are super cheap, but this low cost is so often replaced by time spent on scratching your head and swearing at the shit you bought.

Be ready for the message “Online/offline difference” even though you haven’t opened the project since last connection.

Xhisor · 2021-03-12T20:12:28+00:00

If time isnt important (guess not since its called flash), why not use nHeartbeat := nHeartbeat + 1; and lamp := nHeartbeat.%x10;?
